JOURNAL-BEARING PACKING.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed September 17, 1906. Serial No. 334,898.

To all whom it may concern:

Be it known that I, ADA RoeERs Soo'rT,a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Journal-Bearing Packing, of which thefollowing is a specification.

This invention relates to the packing for journal bearings, to retainthe lubricating material and apply the same continuously to thebearings, and has for its object to provide a packing composed ofcertain materials or substances which when combined and commingledpossess the power of absorbing the lubricating material and transmittingthe same uniformly and continuously to the bearings, and thus obviatingthe danger of the bearing becoming heated by the friction.

With these and other objects in view, which will appear as the nature ofthe invention is better understood, the same con: sists in certain novelfeatures of construction as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, thefigure represents a conventional form of railway axle box, and one ofthe axle journals with the improved packing disposed in the box andbearing upon the journal.

The improved packing herein described and shown may be employedeffectually for all the various journals of machinery. of differentkinds but is more particularly adapted for car axles, locomotlvebearings, automobile axles, dynamo and motor bearings and similarstructures where the bearings are required to support heavy loads andsustain'correspondingly severe frictional strains,

com osed of cotton waste or and consists of a freely intermingled massfiber usually emp oyed in journal boxes and which constitutes acapillary conductor, metal shavings, 'prefera ly steel, which constitutea non-absorbent pressure-exerting and antipacking concomitant and piecesof spon e or like material, which constitute emu sive absorbents toocclude the lubricant and supply the same to the capillary conductor andthus to the bearing continuously and uniformly.

In practice the journal bearing, as for instance a car axle journal asat 10, is incased in the box or casing 11 with the usual well 12 forvthe lubricant, and the improved com- .ing, while the spon e of waste,metal shavings, and s onge the pound inserted in the well and saturatedwit lubricating compound.

The waste material is indicated at 13, the metal shavin s at 14 and thepieces of s onge at 15, and wi 1 be thoroughly comming ed to resent auniform and homogeneous mass.

. his compound possesses the power of cansing the liquid or semi-liquidlubricating material to pass upward therethrough by capillary force, themetal material together with the waste material causin the lubricant tofreely flow upward therefiirough while the sponge plieces absorb thelubricant which expands t e same and thus supplies a larger quantity andpasses it to the journal with suflicient profusion to maintain the sameconstantly lubricated and thereby effectually prevents any tendency ofthe journal to be come heate( no matter how heavy the load may be; Thiscompound of material may be inexpensively manufactured and operateseffectually for the pur oses described.

- The metal shavings y their resilience support the waste and spongeyieldably against the journal bearing and effectually revent anytendency of the parts to pack or ecome sagged in the well portion of thebox or casieces by absorbing a lar er quantity of t e ubricant, verymateria y increase the effectiveness of the pack- Ihe capillaryqualities of the compound are thus materially increased by the coactionof the various ingredients,and its effectiveness as a packing corresondingly increased.

Having thus describer the invention, what is claimed is 1. A journalpacking comprising a freely intermingled mass composed of an emulsiveabsorbent, a capillary conductor, and a nonabsorbent ressure-exertingand anti-packing materia 2. A journal packing comprising a freelyintermingled mass composed of waste, pieces of sponge, and metallicshavings.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature in the presence of two witnesses.

ADA ROGERS SCOTT.
